Abstract
Acute exposure to cannabis has been associated with an array of cognitive alterations, increased risk for neuropsychiatric illness, and other neuropsychiatric sequelae including the emergence of acute psychotic symptoms. However, the mechanisms by which cannabis exposure induces these behavioral and clinical phenotypes remain disputed. To this end, neuroimaging can be a powerful technique to non-invasively study the impact of cannabis exposure on brain structure and function in both humans and animal models. The purpose of the present review is to: 1) provide an update on the findings of pharmacological neuroimaging studies examining the effects of cannabinoids and 2) focus the discussion on studies that examine the sensitive window for the emergence of psychosis. Curren literature indicates that cannabis exposure has varied effects on the brain, with the principal compounds in cannabis (delta-9-tetrahydrocannabinol and cannabidiol) both increasing and decreasing activity in various areas. There are gaps in the literature, especially regarding sex-dependent responses and long-term effects of chronic exposure.
